--------------------------
Key: GERONIMO-6330
URL: https://issues.apache.org/jira/browse/GERONIMO-6330
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Components: specs
Affects Versions: 3.0-beta-1
Reporter: Jarek Gawor
Assignee: Jarek Gawor
When you create an application which contains a JSF mapping in your web.xml
file, JSP (JavaServer *Pages*) files which contain an EL function, throw a NPE.
Here is the web.xml changes I added to a small JSP application:
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
After doing this and deploying the application, the following page throws an
NPE:
hello.jsp:
Test: '${pageContext.getRequest()}'
Exception:
java.lang.NullPointerException
